Case illustration: A 25-year-old woman presenting with radiating pain on her right leg. Preoperative MRI scan showing lumbar disc herniation at the L5-S1 level, right. (A, B) Her BMI was 38.9 kg/m2. Transforaminal ELD was performed, and the symptoms were alleviated. Postoperative MRI scan showing good decompression (C, D).

Case illustration: A 56-year-old woman with arrhythmia, diabetes, and a lumbar disc herniation at the right L4-5 level. The herniation had migrated slightly downward (A, B). Her BMI was 32.5 kg/m2. Transforaminal ELD was performed, and symptoms were relieved. Postoperative MRI scan showing good decompression (C, D).
